Testcomplete™ can be used to automate testing of  Web & windows applications. Although TestComplete™ supports major standard controls, windows and objects in a wide variety of applications, there are some controls and windows that cannot be recognized by Test Complete directly. For example cells in few grid controls, buttons in some flash applications may not be accessible by TestComplete™. Handling TestComplete™ during such conditions makes automation little challenging.

It is possible to overcome these kinds of difficulties by using a low-level recording approach to test such applications. The main drawback of such an approach is that the script will require several changes even for a simple UI change in the application. So, creating and maintaining a stable script with this method is also not possible. Low-level Recording will be usually used in TestComplete™ for automating Testing in browsers other than IE and Firefox.  Any application that needs to be tested in other browsers (such as Google Chrome or Opera) using TestComplete™ automation needs to approach low level recording technique.
